Hi Srdan. The only think you can do in this case is to match on *any* method that has an @NonNull annotation and then use thisJoinPoint.getArgs() in the advice body to expose the arguments from there.
Also you should look at Contract4J, as it does exactly this (and more) using AspectJ: http://www.contract4j.org/contract4j Eric 2008/5/23 srdan bejakovic <[EMAIL PROTECTED]>: > Maybe I'm going about it the wrong way.
